In order to facilitate the installation and the use of the water inlet pipe, the locking piece is bonded at the bottom end of the inner valve core pipe 1, and the resin adhesive is used for better bonding effect because the inner valve core pipe 1 also contains the resin adhesive.
And after S5, the locking piece for locking the water inlet pipe extending into the water inlet channel is placed at the end part of the inner valve core pipe and is connected with the inner valve core pipe after being cast together. Through casting the back with the inner valve core pipe together and link together, remove the step of follow-up installation retaining member from, improve work efficiency.
Preferably, the outer surface of the faucet housing 2 is covered with an insulating layer prior to S4. The outer surface of the tap housing 2 is prevented from reacting with the electrolyte 3.
Preferably, the subsequent installation function of the water faucet is realized, and after electrolysis, the lower part of the water faucet shell 2 is externally threaded.
The product form of the present invention is not limited to the embodiments and examples shown in the present application, and any suitable changes or modifications of the similar ideas should be made without departing from the patent scope of the present invention.
